Mom comes in, sits on the bed with son and references how much fun that graduation gift was 5 years ago, way more memorable than a new car. Anyway, even though I let you get mommy pregnant, I obviously couldn’t carry it to term, your father would have been very suspicious. So I had to get that abortion, and we all just moved on. However, now that your father is no longer with us, and it’s just you and me in the house, I’ve been thinking a lot about that night. I’ve been thinking about how we need to make this family whole again.

What do I mean by that? Well honey, what if… you put your seed in me again, but this time I let it grow?

That’s right honey, I’m saying we should make a baby together! But I won’t abort it this time I promise!

(Mom gets naked and gets on top of son) going slow, riding him while talking about making a baby…

Talk about how your tits will get bigger, and full of milk.
Talk about how plump your belly will get with his seed.
Talk about how you want as many in you as possible, twins would be great!
